What started out as watchmen in Europe in the Middle Ages has turned into the crucial business of security guard and patrol services today. Private or long-term guards can be hired to protect property, assets and people. Locations that are often protected include malls, banks, airports and more. A security guard and patrol company will offer a variety of different services that a person or entity can choose from to meet their needs. Here are some terms that are often used in the industry.

Bodyguard – A bodyguard is a single person or group of specialists who are employed to protect another person from dangers such as assault, kidnapping and more.

Gear – The gear a guard may use could include a baton, mini first aid kit, flashlight, boots, handcuffs and more.

Private – A private guard is hired as an independent contractor by a person or entity that requires protecting. However, company can also hire its own guard as an employee.

Surveillance – There are a variety of surveillance services available including use of video screening, on site patrols and more. Surveillance is often used at a bank, hospital or private home.

Armed – Armed guards carry weapons such as a gun with them while on duty. This high level of safety is needed for high profile corporate executives, at an airport and other top security areas.

Patrol – Patrol services include guards roaming through designated areas that are need of security such as a neighborhood on foot or in a vehicle.

Security guard and patrol services are regularly increasing in demand for many different events and everyday security. These service providers offer safety and peace of mind for private individuals, families and the community.

Although some companies hire their own security guards, most contract with a private company. Patrols are provided by professionals with varying degrees of training.
Security is important to most businesses. Personal security is also a concern amongst the wealthy, and most celebrities hire bodyguards. Corporate security may or may not be armed.
Companies may provide patrols on an ongoing basis or for a specific convention or event. Although they do not have the legal rights or obligations of police, security officers do wear badges and uniforms when on duty. They carry similar gear to law enforcement personnel. Their task is to keep order, usually in public places. Often, these professionals are hired by hospitals, malls, and museums. In the latter two, theft prevention is an important aspect of the role. A gated community, on the other hand, may have security to assist with access control, paid for by the homeowners' association.
In other cases, professionals may be hired for roles other than straight patrols. Bank security, for example, may be involved in the transportation of money and valuables. Bodyguards are hired to protect individuals and their families and homes. A security company that provides personal protection is likely to be different from one which hires 'mall cops'. Airport and marine security personnel are contracted by the government, but often remain somewhat independent.
In many cases, companies hire through a recruitment agency which services this industry. Jobs in security tend to be stable, but with fairly high turnover. Security companies also purchase and provide equipment including protective gear and weapons. Private security companies are often managed by individuals with experience in law enforcement.
Security companies play an important role in handling incidents that might be 'below the radar' of the police.
